Architecture you wear.

The Frederick is what happens when restraint becomes a design language. A wide, structured square silhouette thick Japanese acetate with edges that mean something. No softening, no compromise. The keyhole bridge is tailored, precise, proportioned to hold the whole frame in balance without interrupting it. Deep Eden lenses that turn daylight into something cooler and quieter.

This is a frame for someone who already knows what they like.

A study in proportion.

Barton Perreira describes the Frederick as "a study in balance and proportion" and that's exactly what you feel wearing it. Nothing shifts. Nothing fights. The 47mm eye size sits wide enough to command presence without becoming a statement piece. The 148mm temples land where they should.

Handcrafted in Japan from premium Zyl acetate. Every angle refined over weeks before the frame ever reaches the floor.
